1. Angular Frequency

   Linked via "cycle"

   $$\omega = \frac{2\pi}{T}$$
   This definition establishes the proportionality constant between linear frequency ($f$, measured in Hertz, where $f = 1/T$) and angular frequency. The factor of $2\pi$ arises because one complete cycle) corresponds to a phase change of $2\pi$ radians [2].
